Introduction: Integration of Aircraft Systems

4

Integration of A/C Systems• Aircraft are long living products (40 years) • A lot of upgrade programs, enhancements & national adaptions during their lifetime• Growth of functionality & complexity of the aircraft subsystems• Increase and diversification of A/C variants during lifetimes• New agile development methods

Integration Environment• Complex, rare and expensive test facilities & aircraft components• Compatibility of the integration environment for all integration levels & methods• Reuse of test procedures during system lifetime (regression testing)• Create synergies between different programs & testing methods• Long Term Obsolescence handling for complex

Test environments Test procedures


Introduction: Test Levels and Test Strategies

5

Levels of system integration testing:• System specification & design model testing• S/W and unit testing• Component & subsystem testing• System testing• Virtual system integration• System integration• System qualification & certification

Test & Integration strategies:• Test & analysis of system models (design, specification, S/W)• Development tests using special development tools (agile development)• Functional tests to ensure system operation under all use case conditions• Formal qualification tests for requirement verification • Automated regression tests to ensure system functionality

Objectives for System Test & Integration


Reduce overall project cost for

system development, system integration and system operation

by improving product quality

It is not the primary goal to reduce the cost for system integration & test,but to increase test coverage and quality of testingto find more problems in early integration phases.

Objectives for System Test & Integration


• Increase availability and reduce cost of test environments• Offline (desktop) test preparation & test execution • Agile automatic development testing• Distributed System Integration Remote operation of Test Benches & Test Tools Distributed real‐time testing of real and virtual systems Standards for interoperability & communication (Commands, Data, Time, Files, OSLC …)

• Virtual System Integration Integrate virtual equipment on virtual integration facilities Portability of test procedures between real and virtual test environment Service Based Testing on distributed hybrid computing infrastructure

• Model Based System Integration Test variant management Modelling of Test Scenarios Automatic Test Case generation Tracing of requirements
